Glacier Eucalyptus (Eucalyptus pulverulenta ‘Baby Blue’) is a stunning evergreen tree or shrub prized for its silvery-blue, aromatic foliage. Often used in floral arrangements, this slow-growing eucalyptus is perfect for gardens, containers, and even indoor growing when properly maintained. With its striking round leaves and refreshing scent, Glacier Eucalyptus adds year-round beauty to any space. Here's how to care for this unique plant to ensure healthy growth and longevity.

Lighting Requirements

Glacier Eucalyptus thrives in full sun, requiring at least 6–8 hours of direct sunlight daily to maintain its compact growth and vibrant foliage. If growing indoors, place it near a south or west-facing window to ensure it gets adequate light. If natural light is insufficient, supplement with a grow light.

Soil and Planting Conditions

This plant prefers well-draining, sandy, or loamy soil with a slightly acidic to neutral pH (6.0–7.5).

• For outdoor planting, choose a location with good drainage to prevent root rot.
• If growing in a pot, use a fast-draining potting mix with added perlite or sand to improve aeration.
• Raised beds or containers with drainage holes are ideal for preventing excess moisture buildup.

Watering Needs

Glacier Eucalyptus is drought-tolerant once established but needs regular watering during its initial growth phase.

• Water deeply once a week in the first year to encourage strong root development.
• Once mature, reduce watering to every 10–14 days, allowing the soil to dry out between waterings.
• Avoid overwatering, as eucalyptus does not tolerate soggy roots.

Temperature and Humidity

This eucalyptus variety is relatively hardy, thriving in USDA zones 8–11. It can tolerate temperatures down to 20°F (-6°C) but should be protected from extreme frost.

• If temperatures drop significantly, move container plants indoors or cover outdoor plants with frost cloth.
• Eucalyptus prefers moderate humidity levels but adapts well to drier conditions, making it a great choice for xeriscaping.

Fertilizing

Glacier Eucalyptus is a light feeder but benefits from occasional fertilization.

• Apply a balanced, slow-release fertilizer in early spring to encourage new growth.
• For potted plants, use a diluted liquid fertilizer every 4–6 weeks during the growing season.
• Avoid excessive nitrogen, as it can lead to leggy growth rather than compact, bushy foliage.

Pruning and Maintenance

Regular pruning helps maintain the plant’s shape and encourages fresh, bushy growth.

• Prune lightly in early spring to remove dead or leggy branches.
• Cutting stems back by a third promotes a fuller, more compact habit.
• Frequent harvesting of leaves for floral arrangements naturally keeps the plant tidy and encourages regrowth.

Propagation

Glacier Eucalyptus is best propagated through seeds or cuttings.

• Seed Propagation: Sow seeds in a well-draining seed-starting mix and keep them in a warm, bright location. Germination can take several weeks.
• Cuttings: Take a 4–6 inch stem cutting from a healthy plant, dip it in rooting hormone, and plant in a moist propagation mix. Keep in a warm, humid environment until roots develop.

Common Pests and Problems

While relatively pest-resistant, Glacier Eucalyptus can occasionally attract:

• Aphids – Spray with a strong stream of water or use insecticidal soap.
• Spider mites – Increase humidity and wipe leaves with a damp cloth to prevent infestations.
• Root rot – Prevent by ensuring proper drainage and avoiding overwatering.

Is Glacier Eucalyptus Pet-Friendly?

No, eucalyptus leaves contain compounds that can be toxic to pets if ingested. Keep it out of reach of cats, dogs, and other animals.
